Re: Characterset for Abbrevation names limited

[Wilmar Igl]

Dear Glenn,

thanks for the info. In this case I'd suggest to change the prompt
of global-add-abbrev from e.g.:

M-x Global abbrev for "Desoxyribonucleicacid":

to:

M-x Global abbrev for "Desoxyribonucleicacid" (only letters [a-Z][0-9]):

and/or include a similar comment into the function description.
Otherwise an uninformed user might use the unsupported characters like 
[!"#%&/] and register the failure of the function and interpret it as a bug.

Best,

Wilmar
