We use FormatMessage() to get strings from catalog, get system error messages, etc.
FormatMessage() tends to return Windows* OS-style end-of-lines, "\r\n". When string is printed,
printf() also replaces all the occurrences of "\n" with "\r\n" (again!), so sequences like
"\r\r\r\n" appear in output. It is not too good.
Additional mess comes from message catalog: Our catalog source en_US.mc file (generated by
message-converter.pl) contains only "\n" characters, but en_US_msg_1033.bin file (produced by
mc.exe) may contain "\r\n" or just "\n". This mess goes from en_US_msg_1033.bin file to
message catalog, libompui.dll. For example, message
Error
(there is "\n" at the end) is compiled by mc.exe to "Error\r\n", while
OMP: Error %1!d!: %2!s!\n
(there is "\n" at the end as well) is compiled to "OMP: Error %1!d!: %2!s!\r\n\n".
Thus, stripping all "\r" normalizes string and returns it to canonical form, so printf() will
produce correct end-of-line sequences.
___strip_crs() serves for this purpose: it removes all the occurrences of "\r" in-place and
returns new length of string.
