Except that the reason has nothing to do with the length of file names;
it has to do with the version of the C shell that comes with *some*
System V systems.  Others don't come with any version of the C shell at
all, and still others might conceivably come with a version that
supports "filec".  (Besides, at some times some people might think 14
characters is, relatively speaking, long, so even users of systems
without the BSD file system might want "filec".)

It first appeared in the standard BSD C shell in 4.3BSD.  I presume it
was derived from, or at least influenced by, a similar or identical
function in "tcsh" or some other "non-standard" C shell.
