ERROR: domain error: argument not in valid range

Here is an interesting bug, it took me a while to workout. Apparently modules 4.3.0 does not like "nan" as a directory name. The previous version I was using ( 4.1.3 ) did not suffer from this problem:

[spimcmw@login2 generic]0% module av
ERROR: domain error: argument not in valid range
[spimcmw@login2 generic]1%

[spimcmw@login2 generic]0% mv nan nax

[spimcmw@login2 generic]0% module av
---------------------------- /home/spimcmw/module/generic ----------------------------
admin/d1  nax/d1  sge/8.1.7
[spimcmw@login2 generic]0%

As "nan" is often used for Not a Number, I'd guess this is the root of the problem. I've tracked the issue to an elseif statement, placing $elt in single quotes appears to resolve the problem:

[nanbuild@grid03 modules-4.3.0]0% diff modulecmd.tcl.in modulecmd.tcl.in.orig
6648c6648
<          $modmatch [list '$elt']]]) || (!$wild && ([string match $mod/* $elt]\
---
>          $modmatch [list $elt]]]) || (!$wild && ([string match $mod/* $elt]\
[nanbuild@grid03 modules-4.3.0]1%

I cannot say I've done extensive testing yet, I know that list, load, unload, and switch now work.

nan seems to be a special value that raise an error when returned by expr. Should rework all the expr tests that may return such value.
