A couple more minor typo comments:

Missing word: "as intrinsic" -> "as an intrinsic"
Correction: "implement" -> "implemented"

Correction: "blank" -> "blanks"
Missing word: "as file name" -> "as the file name".

Also, in the rest of the "Arguments" parts of intrinsics.texi, variable 
types like @code{CHARACTER} are not used as nouns, only as adjectives. 
Thus, this should probably be something like "File name, of type 
@code{CHARACTER(*)}.  Trailing blanks are...." to be consistent.  That's 
probably more something to keep in mind for future patches, though, 
since Steve's already approved this one.

(My impression is that, since "minor documentation typo fixes" are 
considered commit-as-obvious for anyone, a version of this patch with 
the one-word typos fixed wouldn't need re-approval; is that correct?)
