======================================================================
Major changes between "less" versions 444 and 449
* Add ESC-F command to keep reading data until a pattern is found.
* Use exit code of LESSOPEN script if LESSOPEN starts with "||".
* When up/down arrow is used on the command line immediately after
typing text, the next command starting with that text is found.
* Add support for GNU regex.
* Add configure option --with-regex=none and fix compile errors
when compiling with no regex library.
* Fix bugs handling SGR sequences in Win32.
* Fix possible crashes caused by malformed LESSOPEN or
LESSCLOSE variables.
* Fix bug highlighting text which is discontiguous in the file
due to backspace processing.
* Fix bug in displaying status column when scrolling backwards
with -J and -S in effect.

standard output. If the input preprocessor does not output a replace-
ment filename, less uses the original file, as normal. The input pre-
processor is not called when viewing standard input. To set up an
input preprocessor, set the LESSOPEN environment variable to a command
line which will invoke your input preprocessor. This command line
should include one occurrence of the string "%s", which will be
replaced by the filename when the input preprocessor command is
invoked.
When less closes a file opened in such a way, it will call another pro-
gram, called the input postprocessor, which may perform any desired
clean-up action (such as deleting the replacement file created by
gram, called the input postprocessor, which may perform any desired
clean-up action (such as deleting the replacement file created by
LESSOPEN). This program receives two command line arguments, the orig-
inal filename as entered by the user, and the name of the replacement
file. To set up an input postprocessor, set the LESSCLOSE environment
variable to a command line which will invoke your input postprocessor.
It may include two occurrences of the string "%s"; the first is
replaced with the original name of the file and the second with the

It is also possible to set up an input preprocessor to pipe the file
data directly to less, rather than putting the data into a replacement
file. This avoids the need to decompress the entire file before start-
ing to view it. An input preprocessor that works this way is called an
input pipe. An input pipe, instead of writing the name of a replace-
ment file on its standard output, writes the entire contents of the
replacement file on its standard output. If the input pipe does not
write any characters on its standard output, then there is no replace-
ment file and less uses the original file, as normal. To use an input
pipe, make the first character in the LESSOPEN environment variable a
vertical bar (|) to signify that the input preprocessor is an input
input pipe. An input pipe, instead of writing the name of a replace-
ment file on its standard output, writes the entire contents of the

To use this script, put it where it can be executed and set

postprocessor can be used, but it is usually not necessary since there
