To whom it may concern:


I have this nasty bug with EFS version 1.15/1.56 in XEmacs 20.4 that
make it virtually unusable. When I try to get a directory listing by
pressing TAB-TAB, I see only part of the files in the directory. Upon
closer inspection, it turns out that the listing stops before a file
that is moderately big (in bytes). Why you ask? Take a look at the
following output in the *Completions* buffer:

Possible completions are:
../  DMixture.h DRotation.h cmodel.h correction.h
./  DMixture.o DRotation.o cmodel.o correction.o
DMixture.cc DRotation.cc cmodel.cc correction.c

Now take a look at the listing produced by EFS in the ftp buffer (I cut
and pasted the ls command to see what happened)

ftp> ls "-al /tmp_mnt/u/bmtln135/jfcrespo/CC/discrim/src/."
/tmp/efsa15896
200 PORT command successful.
150 Opening ASCII mode data connection for /bin/ls.
226 Transfer complete.

Notice the fact that there is no space between the size of the discrim
file and the speechdev group! This is precisely where EFS stopped
looking, as if it believed that there were no more files. I doubt that
this is a coincidence!

Incidently, if I change the group name to something smaller, then it
works like a charm!

Anybody ran into this problem before? Is there a workaround less
intrusive than the one I propose? Should I make an official bug report?
