Hi,

In the set remote exec-file command if we provide space at the end of
the file-name the space is not being cleared. This behaviour is
inconsistent across similar set commands like set logging file etc. My
patch will fix that behaviour. Please review this patch.

Further, I have found that there is a function in cli/cli-utils.c
called remove_trailing_whitespace that never used. In many times we
have removed trailing spaces and for that inline code is written. In
my next patch I am planning to modify the remove_trailing_whitespace
function and use it whenever possible in that. Since that patch will
be relevant to current fix I am proposing, I have mentioned here that
point.

Thanks,
Abhijit Halder
