Hyphenation Check: Further hyphenation is not checked

[mferguson-rpc]

When a hyphenated term was added by hyphenation to another term, it was not flagged in checks (either with the original term or with the new term).

Example:
user-name vs. username is flagged but instances of utf8-user-name and utf8-username in the same doc were not flagged.

This issue and #68 are similar: the checking for hyphenation inconsistencies stops too early. In this issue, the checking stops at the second hyphen. In #68, the checking stops at the whitespace between terms.
