Start counting the line numbers in 1 instead of 0, in case an error
must be printed.
Both the error about a developer entry with no file entry and the error
about a file entry with no developer entry actually belong to the
non-empty line previous the one being analysed, so in these cases print
the line number from the line before.
Also count empty and comment lines, so a developer fixing the file can
jump to the correct line (or the nearest one).
At same time standardize the messages, printing the line number
also in the case of a warning for a file that is not in the tree
anymore.
