Why can you not do this with grep and less?

grep "some string" file1 file2 file3 ... | less

grep "plugin" * | less

(FYI, this was run against the contents of /usr/share/checkbox/jobs/)

audio.txt.in:plugin: user-interact-verify
audio.txt.in: package.name == 'gir1.2-gst-plugins-base-0.10' or
package.name == 'gir1.2-gst-plugins-base-1.0'
benchmarks.txt.in:plugin: local
