l10ntools: GetXrmFile() nearly equal to GetCfgFile()

[Chr. Rossmanith]

Hi,

simian detected 21 duplicate lines in the following files:
l10ntools/source/xrmmerge.cxx
l10ntools/source/cfgmerge.cxx

But as far as I can see the methods GetXrmFile() and GetCfgFile() seem 
to be copy&pasted with minor modifications for ByteString removal and an 
additional exit(-13). It might be enough to have one of them and rename 
it to match both usages in lex files?
