[PATCH 1/1] perf top/report TUI: Provide visual cue when starting annotation

[Arnaldo Carvalho de Melo <acme@kernel.org>]

Sometimes it takes a while for the annotation to be presented after
pressing 'a' in the 'perf top'/'report' TUI, provide a visual cue
informing that the annotation has started for that symbol.

This is the quick and most of the time improvement, but for some cases
its better to improve on it by having a cancellable progress bar, which
is now in my TODO list.
