[PATCH 2/2] Documentation/i18n: quote double-dash for AsciiDoc

[Jonathan Nieder <jrnieder@gmail.com>]

As explained in v1.7.3-rc0~13^2 (Work around em-dash handling in newer
AsciiDoc, 2010-08-23), if double dashes in names of commands are not
escaped, AsciiDoc renders them as em dashes.

While fixing that, spell the command name as "git sh-i18n--envsubst"
(2 words) instead of emphasizing the name of the binary (one
hyphenated name) and format it in italics.

 passed to the the `eval_gettext` function.
