it is used by t->proc->abi->fetch_args().
Without that truss is segfaulting and the attached program also crash.

or "+" (these are invalid, because there is no preceding operand).
When bsdgrep attempts to emulate GNU grep in discarding and ignoring the
invalid ? or + operators, some later logic in tre_compile_fast() goes
beyond the end of the buffer, leading to a crash.
Fix this by bailing out, and reporting a bad pattern instead.

While big, the change was meant to have no effect on behavior and instead
so far we have found two regressions: one in the etcupdate tests and
another one in the games/openttd port[1].
Revert to a known working state. We will likely have to split the patch in
functional parts before bringing back the changes.

clang-analyzer complained that eqin() sets file-scoped pointer param_start
to point into char buffer defined in scan_profile(), and once
scan_profile() exits, param_start is a "dangling reference". param_start
was never used afterwards, but it's cleaner to move it to set_option()
which is the only branch where param_start is needed.

It's pr_comment.c that should decide whether to put a "star comment
continuation" or not. This duplicates code a bit, but it simplifies
pr_comment() at the same time since pr_comment() no longer has to "signal"
whether a star continuation is needed or not.
This change requires indent(1) to not wrap comment lines that lack a blank
character, but I think it's for the better if you look at cases when that
happens (mostly long URIs and file system paths, which arguably shouldn't
be wrapped).
It also fixes two bugs:
1. Cases where asterisk is a part of the comment's content (like in "*we*
are the champions") and happens to appear at the beginning of the line,
misleading dump_line() into thinking that this is part of the star comment
continuation, leading to misalignment.
2. Cases where blank starred lines had three too many characters on the
line when wrapped.

After a blank line was printed (to separate paragraphs in comments), the
next line was sometimes wrapped to the column at which the previous
non-empty line ended. The fix is to reset the last blank pointer (last_bl)
on newline.

Modify count_spaces() to take a third parameter "end" that will make the
function return when the end is reached. This lets the caller pass a
pointer to non nul-terminated sequence of characters. Rename
count_spaces() to count_spaces_until() and reinstate count_spaces(), this
time based on count_spaces_until().
Use count_spaces_until() to recalculate current column when going through
a comment just before the fragment which decides if current line of the
comment should be wrapped. This move simplifies this code by eliminating
the need for keeping the column counter up to date every time e_com is
advanced and also reduces spread of code that has to know how many columns
a tab will produce.
Deduplicate code that decided if a comment needs a blank line at the top.

The original indent(1) described unix-style comments as similar to box
comments, except the first non-blank character on each line is lined up
with the '*' of the "/*" which appears on a line by itself.
The code has been turned off for ages and -sc/-nsc make it even
less relevant.

This fixes a very visible issue that may be hidden by some indent.pro
settings as in the example from FreeBSD's /usr/share.
From Piotr's log:
____
To prevent losing tabs from indentation in declarations, FreeBSD indent's
r125624 added code for the most common case when it's an identifier that
is indented, but didn't do anything with the original code that did the
same for any other cases. The other cases are: lparens (function pointer
declaration), asterisks (pointer declaration), stray semicolons, and
commas leading identifiers instead of trailing them.
Use the code added in r125624 (and improved in later commits) to write a
new function indent_declaration() and use it in all places that meant to
indent declarations. In order to indent only once per line, reuse existing
ps.dumped_decl_indent variable that was only used when formatting for
troff (-troff) until now.

This piece of code removed tabs and space characters from after colons
that follow labels by decrementing the e_lab (end of label) "pointer"
which is later used to calculate the width of the string that fprintf()
puts into "output". But pad_output() gets the length from the actual
string, so it miscalculated what the current column is.
Fixed by putting a string terminator at the e_lab "pointer".

Pull a copy of the filename string before calling basename(). Change the
loop to not return on its own, so we can put a free() statement at the
bottom.
POSIX allows these functions to modify their input buffer, so that they
have storage for the return value. Pull copies of the filename before
calling these utility functions.
which is more efficient.
Note that for now we do not create a separate library for libdivsufsort
because it's not used anywhere else.
