Leading dashes at the start of a lemma/word

[IvyJL]

For example, enclitics beginning with a hyphen
and a word that lacks a nom. sg. like —, sui, sibi, se, se

ne2 -ne
que -que
ve -ve
sui —, suī, sibi, sē, sē

[jaguillette]

As a user, when I upload a vocabulary list, I should be able to include enclitics like "-que" and special cases like "—, suī, sibi, sē, sē". Currently these may not match to lemmas. Should match on first word-like thing, even if first thing is not a word.
