digraphs: ignore ansi commands in vim version output

Recent versions of Vim v7.4 prepend the expected version number by various
escapes (probably terminal-dependent), causing an unreadable result of:

	\e[?1049h\e[?1h\e=\e[1;63r\e[?25h\e[?25h\e[?25l\e[63;1H704

Assume nothing is put after the wanted number, so capture only that.
