Fix inconsistent "Watching for changes in [path]" output with hugo server #1721
Description
The printed watched paths look kind of weird when --source is a relative directory. For example:
foka@debian:~/git/hugo$ hugo server -s docs
0 draft content
0 future content
166 pages created
0 paginator pages created
41 tags created
0 groups created
in 409 ms
Watching for changes in docs/docs/{..}
Serving pages from memory
Web Server is available at http://localhost:1313/ (bind address 127.0.0.1)
Press Ctrl+C to stop
foka@debian:~/git/hugo$ cd docs
foka@debian:~/git/hugo/docs$ hugo server
0 draft content
0 future content
166 pages created
0 paginator pages created
41 tags created
0 groups created
in 425 ms
Watching for changes in /home/foka/git/hugo/docs/{data,content,layouts,static}
