Documentation contains incorrect letter case for some command-line parameters

[Dmitro25]

"Instructions for objconv" file contains the following text:

-fXXX Convert file to format XXX. XXX = COFF, OMF, ELF or MAC.
PE is accepted as a synonym for COFF. The word size, 32 or 64, may be
appended to the name, e.g. ELF64

When I try to use command-line parameter -fOMF (case sensitive) I get an error "Error 2004: Unknown command line option: %sfOMF".
After some attempts I understand that it is correct to type "-fomf" (may be it is right only under Windows, I don't know).

Windows 10, objconv v2.47
