Since lohit-devanagari-fonts doesn't provide any rules for monospace and serif,
this is just a kind of FYI.

Looking at the above result, there seems some issues here.

 * paktype-fonts appears because it doesn't have the locale-specific overrides
rule.
 * fontconfig doesn't take care of the difference of ll and ll at scriptname.
 * most rules in this config file matches any of the above.
 * fontconfig says Lohit Devanagari supports Bihari and Bhojpuri though, no
rules for that.

Last two are issues in lohit-devanagari-fonts. though it's separate issues with
this however.

Anyway, *this* issue itself seems gone with the fix though.
