Fix to HdrRule to handle '#include "path/file"': if the included
file has a directory component, then SEARCH and HDRSEARCH are set
to include the previous HDRSEARCH with 'path' appended. Without
this, then any files included by "path/file" might not be found
by jam, as it didn't know to look in the 'path' subdirectory.
This is needed for p4v's central 'windows' include file.
