revisions.txt: consistent use of quotes

Our use of quotes is inconsistent everywhere and within some files.
Before reworking the structure of revisions.txt, make the quotes
consistent:

`git command`

'some snippet or term'

The former gets typeset as code, the latter with some form of emphasis.
the man backend uses two types of emphasis.
