* grep_proc.cc: When a request is queued with the start line
== -1, we need to start searching from the highest line
ever seen and not the last line processed.
* line_buffer.cc: If a partial line was read, we need to
avoid returning another line if more data is appended
to the file.
* lnav.cc: Accept file name patterns on the command-line that
don't match any files yet. Initialize the screen before
redirecting stderr to the log file or /dev/null.
* log_format.hh: Add some comments. Start to add back support
for scrubbing.
* logfile_sub_source.cc: Move scrubbing to the format impl.
* textview_curses.hh: Add comments.
The cygwin build is pretty straightforward, but there's
still some glitches that need to be fixed.
* line_buffer.hh, line_buffer.cc: If the bzip library is not available, don't
try to open bzip files. Also, ignore ENODATA errors since they seem to
show up when pread reaches the end of the file.
* lnav.cc: The abs() function is ambiguous on windows, use std::abs instead.
