So far, yes. All abbreviations that have cyrillic letter р anywhere
within its text does not expand, and so far I can not find another
cyrillic letter that produces the same disorder.

Probably, it is because the letter р is special: many "cyrillic"
children cannot pronounce the corresponding sound for years and
substitute it with л. :)

Thank you for solving this problem, Christian.

I am not going to apply your patch myself but will wait until it finds
its way to the official release of Vim.
