Right.  Looking at the pdf output of this:

\version "2.13.3"
\new Staff \with {
  instrumentName = "this is a really really long instrument name"
}{
  c'
}

I only see "rument name" to the left of the staff; the rest runs
off the left-hand side of the pdf page.  Printing text outside of
the page margins (let alone the page itself!) is bad.

Phil is trying to solve this by automatically increasing
  \paper{ indent=5\cm} }
so that there's enough room to print the instrument name.  (5cm
picked randomly; it's intended to be long enough to print "this is
a really really long instrument name")

Changing the indent is not necessarily the best solution (although
I can't think of anything better), nor is his approach necessarily
the best method of implementing it.  But the bottom line is that
the above example produces a sucky pdf right now.
