Smart indent matches partial command matches

The basic-language support in ChoicescriptIDE/monaco-editor defines the "smart" indentation behaviour based on RegExes.
Whilst implementing *ifid I noticed that it's incorrectly treated as a indenting command, because the 'if' part is matched.
Unfortunately this seems to extend to invalid commands as well, for e.g.:

*ifishouldnotiwouldnot

Will trigger an automatic indent.
