[gnuastro-commits] master d9949bf7: Installed scripts: unified error message formats

[Mohammad Akhlaghi]

branch: master
commit d9949bf72c41027909d597ad4b83821d507290a9
Author: Mohammad Akhlaghi <mohammad@akhlaghi.org>
Commit: Mohammad Akhlaghi <mohammad@akhlaghi.org>

    Installed scripts: unified error message formats
    
    Until now, some of the error messages in the installed scripts started with
    'ERROR:' after the script script name. But this is not a convention within
    Gnuastro's programs (or in the GNU Coding Standards in general). Also, when
    checking the '--*center' option value, some of the scripts did not print
    the original string! Further more, one of the error messages ended with a
    '.' (which is against the GNU Coding Standards).
    
    With this commit, all the problems above have been fixed.
