[Tarantool-patches] [PATCH luajit] tools: make memprof parser output user-friendly

[Sergey Ostanevich]

Hi!

Thank you for the patch and review!

Let me propose some technical fix:

long/path/to/function.lua: 3 events
very/long/path/to/function.lua:	3 events

I think dump as above is not-so-readable for humans. A single-symbol fixup gives 

long/path/to/function.lua:	3 events
very/long/path/to/function.lua:	3 events

+    print(string.format("%s:\t%d events\t+%d bytes\t-%d bytes",

The better solution would be to keep the longest name and append/prepend all of them
with spaces, so that the following will not happen:

long/path/to/funct.lua:	3 events
very/long/path/to/funct.lua:	3 events


All of these are too much ‘vkusovschina’, so you have my LGTM.

Sergos
