Comment 7 for bug 1955450

In revision 632 I standardized the three MarkupResemblesLocatorWarning texts to consistently use "may want to" language instead of the more judgmental "probably should" language. Previously the language was inconsistent, and "may want to" language was used only in situations where the markup was the name of a directory on disk.

I'm not going to add an argument to an already crowded method signature (and document it and support it forever) when Python already has a standard mechanism for suppressing warnings of a certain type across a running process.
