Rearranging old ChangeLog files

[Joseph S. Myers]

Among the files with trailing whitespace I didn't deal with in my general 
cleanup are ChangeLog.{1,2,3,4,9}.

(a) Does it seem appropriate to clean up trailing whitespace in these 
files?

(b) Various other GNU projects now arrange past ChangeLogs by year rather 
than with numbers 1, ..., 17.  Would it seem appropriate to rearrange 
glibc's ChangeLogs like that (ChangeLog-1991, ..., ChangeLog-2012, with 
the main ChangeLog having the entries starting at the start of 2013 and 
being rotated annually)?
