I concur with Steve.

However, I would like to point out one possible problem with basename
in this regard -- many basename executables are /bin/sh scripts which
call expr three times.  On my machine, the difference in speed between
the /bin/sh-based system basename and the pure-binary GNU basename is a
factor of 4 (which is the difference in the number of fork/exec
pairs).  

Anything based on ifs separation will probably come to grief on file
names containing repeated dots, such as `foo..bar'.

Alan.
