Then the comment was plain wrong (not misplaced), so removing it becomes 
right again because the comment states: "opendir()'s comparison function" 
according to POSIX 2008 and XSI 7 should use strcoll(). But there is 
nothing said about opendir() & strcoll() relation in the mentioned 
standards. The only word I found is that opendir() returns "ordered" 
sequence, but nowhere mentioned ordered by what criteria, so perhaps they 
mean "stable":

"The type DIR, which is defined in the <dirent.h> header, represents a 
directory stream, which is an ordered sequence of all the directory 
entries in a particular directory."

Alphabetically already means sorted according to collate, otherwhise it is 
called binary. Perhaps manpage should refer strcoll() directly.

I don't add extra "the" there) What do you want, clarify please:
1) Remove whole comment.
2) Remove only first line and correct second to "that".
3) Just correct second to "that".
