Wouldn't you know it?  After more than a month of silence from beta testers I
finally decided to post shar 3.43 to alt.sources.  Only a few hours later a
bug report showed up!  Moby sigh.  Anyway, here is the fix for a minor bug
and an enhancement.

1) A line containing just "SHAR_EOF" in an input file now gets an 'X' prepended
in the output file even if -F is not specified.

2) The new compile-time definition NO_DIRENT indicates that the SunOS3-style
<sys/dir.h> should be used instead of Gwyn-style (or equivalent) <dirent.h>.

Thanks to Frans Meulenbroeks (meulenbr at cst.philips.nl) for reporting the two
problems.
