A bug report from ten and half years ago...
If a carried egg hatches, the message is
|<foo> drops from your pack.
and if tame, is followed by
|Its cries sound like {mommy,daddy}.
The latter was issued even when <foo> has no speech capability.
Replace "its cries sound like" with "its <vocalize>ing sounds like"
for suitable value of <vocalize>.
This adds two new monster sounds, MS_BELLOW and MS_CHIRP, also two
new sound effect codes, se_chirp and se_croc_bellow.
We had MS_SILENT for crocodile. On wikipedia, crocodile is described
as the most vocal reptile. Adult males make a load bellowing noise
and hatchlings make a chirping noise.
This changes crocodile, titanothere, and baluchitherium from MS_SILENT
to MS_BELLOW and baby crocodile from MS_SILENT to MS_CHIRP. Chirp
might be appropriate for lizards and lizard-like amphibians but I've
left those as MS_SILENT.
[Noticed but not changed: lizards and lizard-like amphibians aren't
flagged as oviparous. Shouldn't they be?]
