I am not sure if this is good way to check if ctags supports "-e" or not.

+ then ctags --version 2>&1 | grep -- -e >/dev/null

Perhaps, "--help" might be intended rather than "--version" to check
supported options? Even so, ctags would have other option whose name contains
"-e" than Emacs support, so this check could end in a wrong result. Therefore,
it seems to me that it is better to check immediately if etags is available
in case that we don't have Exuberant-type ctags.
