on OSX, wildcard "*" seems to be not enforced when open a file

[alaingdl]

Assuming file "titi" is the only one in the working dir.

What we get in current GDL on Linux or IDL on OSX and Linux

GDL> cd, '/tmp
GDL> $touch titi
GDL> res=FILE_INFO('tit*')
GDL> res1=FILE_INFO('titi')
GDL> print, res, res1
{ titi   1   1   1   0   1   0   0   0   0   0   0   0   0   0   0         436            1784198919            1784198919            1784198919
                     0}
{ titi   1   1   1   0   1   0   0   0   0   0   0   0   0   0   0         436            1784198919            1784198919
            1784198919                     0}
GDL> openr, unit,/get_lun, 'tit*' & print, unit
    100

What we get on OSX + current GDL

[...]
GDL> print, res, res1
{ tit*   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0           0                     0                     0                     0
                     0}
{ titi   1   1   1   0   1   0   0   0   0   0   0   0   0   0   0         420            1784198818            1784198818
            1784198818                     0}
GDL> openr, unit,/get_lun, 'tit*' & print, unit
% Error opening file. Unit: 100, File: tit*

I detected that trying to read a FITS file with wildcard *
I suspect some troubles related to the famous WordExp() 😿

I don't know if is related to some troubles I have with recent Readline versions on OSX ...
