Dynamics and arpeggios too close to bar lines

[Benedict Singer]

Hi all,

It's been a while since I've been on this list, but now with a 
composition teacher, I'm using Lilypond regularly again. Thus, I have 
some questions about a few issues that have been bugging me, having to 
do with music elements too close to or overlapping with bar lines. This 
is with version 2.10.33. The first of these is arpeggios on the first 
note of a bar; the arpeggio squishes right up against the bar line, 
making it hard to read. This problem could be solved by moving to 2.11, 
which I just tested; however, I'd prefer to stay on the stable branch. 
Also, my second problem was not solved by 2.11. This relates to dynamics 
in the Piano centered dynamics template. Hairpins and dynamic marks tend 
to brush right up against, or even overlap (the mp mark is one of the 
worst) the bar lines. If there's one tweak involving bar lines that 
would solve both these problems, then that would be great; however, from 
a quick look at the reference docs on bar line objects, nothing was 
obvious. Alternatively, tweaks to the arpeggio objects or the dynamic 
objects would work instead. Thanks in advance guys!
