Modify Task Tag(s)
modify_tag.RdThis is a package internal function to modify tags of a task (in the
todo.txt definition properties prefixed with + or @).
Note that by suitably setting the old and new value, specific effects
like removing a tag or adding an additional tag. For instance, by setting
the old value to the end-of-line regular expression $, a tag can be
appended. Note that this may result in adding superfluous spaces.
