[gnumeric] Docs: ignore initial whitespace in function argument documentation.

[Morten Welinder <mortenw src gnome org>]

commit 5f4d7c3353d1bc0798693b69797cdd1af79aa89c
Author: Morten Welinder <terra gnome org>
Date:   Mon Apr 30 14:05:58 2012 -0400

    Docs: ignore initial whitespace in function argument documentation.
    
    We expect "arg:desc", but translators sometimes assume that the
    two parts are shown together and translate to "arg: desc".  With this
    change, we don't care.
