Below is a patch for setwd() to show path in error message. Current
it just gives error messages such as:
Error in setwd(libdir) : cannot change working directory
with the patch it should (read untested) give:
Error in setwd(libdir) : cannot change working directory to 'path/that/fails/'

TRANSLATIONS:
I have zero experience with GNU gettext/*.po files, but I understand
that the above change requires updates to src/library/base/*.po files,
which now looks like (e.g. de.po):
#: src/main/util.c:699 src/main/util.c:706
msgid "cannot change working directory"
msgstr "kann Arbeitsverzeichnis nicht wechseln"
A generic/automatic update would be to use the format:
#: src/main/util.c:699 src/main/util.c:706
msgid "cannot change working directory: '%s'"
msgstr "kann Arbeitsverzeichnis nicht wechseln: '%s'"
but I don't think that is in line with the current R style.
