g.remove WXGUI interface causes buffer overflow in g.findfile

[marisn]

Steps to reproduce:

• launch g.remove and select a lot of raster maps from list. In my case it resulted in 280 symbol long comma separated list for rast= parameter.
• RUN :)
• Copy command and run from CLI just fine without any problems.

My GRASS version could be like r53972

Should be fixed according to #2091.
