[Rd] getParseData() for installed packages

[Kirill Müller]

I can't seem to reliably obtain parse data via getParseData() for 
functions from installed packages. The parse data seems to be available 
only for the *last* file in the package.

See [1] for a small example package with just two functions f and g in 
two files a.R and b.R. See [2] for a documented test run on installed 
package (Ubuntu 15.10, UTF-8 locale, R 3.2.3). Same behavior with 
r-devel (r70303).

The parse data helps reliable coverage analysis [3]. Please advise.


Best regards

Kirill
