Ok, I've updated my patch to that 'eshell-integer-regexp' is just a 
regular defvar. In the second patch, I also converted 
'eshell-number-regexp' to a defvar, and improved the regexp to match 
more valid numbers. I think with those improvements, there's no real 
reason for 'eshell-number-regexp' to be customizable anymore.

Note: I haven't done anything with the range syntax though. If you feel 
strongly that it should be a closed range like in Bash (instead of 
half-open like it is in the current patch), then I don't mind changing 
it. Personally though, I have a soft preference for half-open since it's 
more consistent with the rest of Emacs Lisp.
