[tex-k] -fmt doesn't work on 7.4.2

[David Necas (Yeti)]

Hello,

the -fmt option of (pdf)tex doesn't work for format creation
in 7.4.2, or I'm doing something really stupid.  E.g., the
pdfcsplain format is normally generated

pdftex -ini -fmt pdfcsplain -progname pdfcsplain csplain.ini

This creates pdfcsplain.fmt on 7.3.7 (as expected), but
csplain.fmt on 7.4.2.  Generally, command

tex -ini -progname bar -fmt foo spam.ini

generates spam.fmt, while I would expect foo.fmt.

Regards,
