Refer consistently to software versions.  In most cases, it is done as
<software> <version>.  In the case of Linux and glibc, use the project
name, instead of other terms such as 'kernel' or 'library'.

I found the uses of inconsistent language with the following:

$ find man* -type f \
| xargs grep -i '\(since\|before\|after\|until\|to\|from\|in\|between\|version\|with\) \(kernel\|version\|2\.\|3\.\|4\.\|5\.\)' \
| sort

However, I might have missed some cases.  Anyway, 99% consistency is
pretty good consistency.  We'll fix the remaining cases as we see them.
