PR 21741: Christian Biere: Buffer overrun and wrong usage of islower() in
less 381
Over three years ago the less maintainer said he'll add these fixes.
Nothing happened, so we do it ourselves.
Thanks for the report and the patch!
----------------------------------------------------------------------
Bump PKGREVISION.
changes since 378:
* New -L option to disable LESSOPEN processing.
* Further support for large (64 bit) file addressing. Large file
* support is now set up by the configure script.
* Use autoconf 2.54. Replace configure.in, acconfig.h,
* defines.h.top with configure.ac.
* Overstriking underscore with underscore is now bold or
* underlined depending on context.
* Use only 7 spaces for line numbers in -N mode, if possible.
* Fix some bugs in handling overstriking in UTF-8 files.
* Fix some nroff issues in the man page.
Changes since less-376:
* Bug fixes:
Default buffer space is now 64K as documented.
Search highlighting works properly when used with -R.

See the NEWS file for the full list of changes.
Update MASTER_SITES and HOMEPAGE.
Changes since 358:
* -x option can now specify multiple variable-width tab stops.
* -X option no longer disables keypad initialization.
New option --no-keypad disables keypad initialization.
* New commands t and T step through multiple tag matches.
Added support for "global(1)" tags
(see http://www.gnu.org/software/global/global.html).
* New prompt style set by option -Pw defines the message printed
while waiting for data in the F command.
* System-wide lesskey file now defaults to sysless in etc directory
instead of .sysless in bin directory.
Use "configure --sysconfdir=..." to change it.
(For backwards compatibility, .sysless in bin is still recognized.)
* Pressing RightArrow or LeftArrow while entering a number now shifts
the display N columns rather than editing the number itself.
* Status column (enabled with -J) now shows search results.
* Improved performance in reading very large pipes.
* Eliminated some dependencies on file offets being 32 bits.
* Fixed problems when viewing files with very long lines.
* Fixed overstriking in UTF-8 mode, and overstriking tabs.
* Improved horizontal shifting of text using -R option with ANSI color.
* Improved handling of filenames containing shell metacharacters.
