Subject: Accept list of separators as a wxString instead of wxChar\nTurn NextNonWhiteSpace... 
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/191549ed17cc522034a85bc6f313d47335302e7e

Accept list of separators as a wxString instead of wxChar\nTurn NextNonWhiteSpace to NextNonSeparators\nIntroduce EatEOL (major factorization)\nFix GetC() call on last char introduce a bug
