Return always malloc()-ed strings from VarParseShort() to get
rid of warnings when returning string constants from a non-const char *
function.

Eliminate code that is now obviously dead.

just before the return statements.

after a return. Move assignments to {freePtr, dynamic, start} closer to the
return statements to clarify which variables are actually used for
communication between the losely coupled blocks of the code. Clear up
an if-expression to make common structures of the conditions clearer.
Use strchr instead of switch statements to check for a character beeing
a member of a set.

are not needed and which can easier be split out.

shift a break around and add braces where appropriate.

Move some assignments nearer to where they actually used. Convert a loop
from a for() to a while() to make it clearer and add braces to the long
body of it. Split assignment from variable declaration.

mess of Var_Parse. Rewrite a for() loop into a while() to make it clearer.

means if Ptr is a pointer to a struct).

that get included just where they are needed. All headers include the
headers that they need to compile (just with an empty .c file). Sort
includes alphabetically where apropriate and fix some duplicate commenting
for struct Job, struct GNode and struct Shell by removing one version and
inlining the comments into the structure declaration (the comments have been
somewhat outdated).
This patch does not contain functional changes (checked with md5).

now that their size is only two pointers. This eliminates a lot of calls
to Lst_Init and from there to malloc together with many calls to
Lst_Destroy (in places where the list is obviously empty). This also
reduces the chance to leave a list uninitilized so we can remove more
NULL pointer checks and probably eliminates a couple of memory leaks.
requires to make a copy of the filename in ReadMakefile and to duplicate
two small functions in suff.c. This hopefully will go away when everything
is constified.
