Re: [jira] [Resolved] (SVN-4660) svn info --show-item=revision produces trailing whitespace

From: Stefan <luke1410_at_gmx.de>

Would it be better to only list 1.9.5 as fix version in such cases?
I mean: It's practical implicit that any fix present in a released
version is also present on trunk, no?

XXX was retrieved using --show-item=revision. Since that produced unexpected trailing whitespaces the script command resulted in [...] -rXXX :YYY [...] which obviously caused an error message which was hard to debug since I didn't immediately get the idea that the trailing whitespaces might cause the script error I saw.
