Using DotGlob directly in constructing MPath pointers can violate the Pointer string round-trip contract because some dot globs cannot be represented in parsable form.

To address this bug, this issue proposes an enhancement feature where quoted strings can have a prefix to specify the string is parsed as a DotGlob:

/"hello world" stays as an exact member
/g"hello*world" is a regular glob but quoted
/g"hello world" represents a wildcard-free glob
/g"" would be an empty glob

In implementation, the tokenizer should allow a prefix of any length. The parser should accept no prefix for DotExact and g for DotGlob, where other prefixes should error. This allows for future prefix r for regular expressions #4.

Conversion of DotGlob to a string should omit the prefixed string representation when unnecessary but use g"..." when there is an absence of wildcards.

Character escaping is as expected:

* and ? are wildcards.
\* and \? are literal characters.
\" represents a quote.
\\ represents a backslash.

Implemented in 9a56957 as described. It was implemented in such a way that other prefixes can be easily added, such as r for regular expressions in the future. Round-trip string tests were updated too.
