Rats.  You have the threshold for the shrinking significantly lower
than readmax in process.c?

Which is normal.  I probably should try to weazle around producing
this message since people tend to get surprised by it.

Quite so.

So let us compare our language environments:

Latin-1 language environment

[...]

Character sets:
  ascii: ASCII (ISO646 IRV)
  latin-iso8859-1: Right-Hand Part of Latin Alphabet 1 (ISO/IEC 8859-1): ISO-IR-100.

Coding systems:
  iso-latin-1 (`1' in mode line):
	ISO 2022 based 8-bit encoding for Latin-1 (MIME:ISO-8859-1).
	(alias: iso-latin-1 iso-8859-1 latin-1)
