Description of problem:
When trailing whitespace exists on a line in an rpmrc file, it is not 
stripped before the value is used by other parts of RPM.



Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:

Here is how I encountered this problem. I had this line (enclosed in 
quotes to show trailing whitespace) in an rpmrc file:

"macrofiles:     /usr/lib/rpm/macros:/usr/lib/rpm/%
{_target}/macros:/etc/rpm/macros.specspo:/etc/rpm/macros.db1:/etc/rpm/macro
s.cdb:/etc/rpm/macros:/etc/rpm/%
{_target}/macros:~/.rpmmacros:/root/build/kernel/rpmmacros "

RPM attempts to open the "/root/build/kernel/rpmmacros " file, which of 
course does not exist. I was able to see RPM attempt to open the file with 
the space on a systrace, shown here:

open("/root/cvs_explore_source/rpmmacros ", O_RDONLY) = -1 ENOENT (No such 
file or directory)

I wanted RPM to attempt to open the "/root/build/kernel/rpmmacros" file.

Actual Results:  RPM attempted to open the 
file "/root/build/kernel/rpmmacros ". (See above description.)

Expected Results:  RPM should have attempted to open the 
file "/root/build/kernel/rpmmacros". (See above description.)

Additional info:

I don't know if whitespace really *should* be stripped from the ends of 
entries in rpmrc files. Since the whitespace between the attribute and the 
colon and the value is stripped, I would expected that trailing whitespace 
should be stripped as well.

I looked in the documentation and was not able to find a definition of how 
an rcfile should act with trailing whitespace.

I did find this, however, which defines that whitespace should be stripped 
for entries in macro files. 

From /usr/share/doc/rpm-4.0.3/macros:

} To define a macro use:
} 
} \verbatim
}         %define <name>[(opts)] <body>
} \endverbatim
} 
} All whitespace surrounding <body> is removed.  Name may be
} composed of alphanumeric characters....

The fix -- when attempted -- will be to remove rpmrc configuration
entirely.

Meanwhile, the workaround is
	Don't do that.
