Bugs in less-354

This is a list of the known bugs in less-354.

#101

Using the -s flag can put "~" lines before the beginning of the file.

#104

Using the -s flag on a file with trailing blank lines, type the "G" command. The prompt may say "99%" instead of "100%".

#130

Command "F" doesn't work if the file shrinks in size.

#138

On Solaris, searching for "a[1,2]" matches "a4".

#152

On a Solaris cmdtool, slow pipes get stalled and never show any data.

#174

Cannot search for a string which follows a null byte ('\0').

#185

On some terminals, arrow keys don't work when you set -X.

#192

In certain cases, when built with a non-POSIX regular expression library, if search highlighting is enabled and a search pattern begins with a ^, more text than the matching string may be highlighted.

#193

On some systems which use setlocale() and the LC_* environment variables, less treats some binary files as ordinary, non-binary files. You can workaround this problem by setting the environment variable LESSCHARSET to "ascii" (or whatever character set is appropriate).

#200

On Windows NT, if the screen buffer is larger than the displayed window size, lines can "leak" into the offscreen part of the buffer. (If any Windows expert can help me with this one, I'd appreciate it.)

#201

The DOS version compiled under DJGPP cannot open long (non-DOS) filenames when run on Windows-NT.

#203

The Windows version compiled under Microsoft Visual C++ sometimes highlights incorrectly when a highlighted line is longer than the screen width. (If any Windows expert can help me with this one, I'd appreciate it.)

#211

You cannot open a file that starts or ends with a double quote.

#226

There is a race condition when less is in a pipeline and a signal is sent to all processes in the pipeline. In this case, less and another process may try to change terminal attributes at the same time.
