tla has been very correct in its error messages; which this one (from your 
description) seems to fit right into.
It would be nice if the error message would end with a suggestion to get the 
user on its way to solve the problem.

So in addition to 'No such revision' it would be nice to print on a second 
line (to stderr)
"check valid revisions using 'tla revisions'"
Alternatively (less nice, but more in line with current tla)
"  (try 'tla revisions')"


Just to be complete; I would really like to see more intelligent error 
messages where possible; a few examples:
 $ tla abrowse -A sftp://myserver/some/path
invalid archive name sftp://home/zander/sources/archives

Could additionaly give:
"Is the archive registered, see 'tla archives' and 'tla register-archive'"


 $ tla register-archive address@hidden sftp://wrongFoo/wrongPath
 $ tla abrowse -A address@hidden
ssh: : Name or service not known
Error reading from server

Could additionaly give:
"Check if registered archive is correct, see 'tla archives'"

Just my 0.02
