Subject: [PATCH] perf tools: handle spaces in file names obtained from

Steam frequently puts game binaries in folders with spaces.
Note: "(deleted)" markers are now treated as part of the file name.
It probably worked before 6064803313bad9ae4cae233a9d56678adb2b6e7c
("perf tools: Use sscanf for parsing /proc/pid/maps").
