filemerge: introduce a 'regkeyalt' merge tool variable
This allows us to provide alternate search keys for 64bit operating systems that
may have 32bit merge tools installed. Presumably it may find other uses.
Translations are optional:
$ "$TESTDIR/hghave" gettext || exit 80
Test that translations are compiled and installed correctly.
Default encoding in tests is "ascii" and the translation is encoded
using the "replace" error handler:
$ LANGUAGE=pt_BR hg tip
abortado: N?o h? um reposit?rio do Mercurial aqui (.hg n?o encontrado)!
[255]
Using a more accomodating encoding:
$ HGENCODING=UTF-8 LANGUAGE=pt_BR hg tip
abortado: N\xc3\xa3o h\xc3\xa1 um reposit\xc3\xb3rio do Mercurial aqui (.hg n\xc3\xa3o encontrado)! (esc)
[255]
Different encoding:
$ HGENCODING=Latin-1 LANGUAGE=pt_BR hg tip
abortado: N\xe3o h\xe1 um reposit\xf3rio do Mercurial aqui (.hg n\xe3o encontrado)! (esc)
