Line wrapping with different font sizes

[annaswims]

I'm working someone who uses a larger font size in his terminal. He is hosting the terminal session. Rather than wrapping the text to the next line it wraps to the same line and overwrites the beginning of his prompt. I see:

~/nextgear/activerecord-sqlserver-adapter [rails-4] $ cip
thirdshift::activerecord-sqlserver-adapter::_ 
verecord/test/cases/migration/columns_test.rbails-4] $ be rake test TEST_FILES=/Users/garretthart/nextgear/source/annarails/activ

but I would expect to see:

~/nextgear/activerecord-sqlserver-adapter [rails-4] $ cip
thirdshift::activerecord-sqlserver-adapter::_ 
~/nextgear/activerecord-sqlserver-adapter [rails-4]  $ be rake test TEST_FILES=/Users/garretthart/nextgear/source/annarails/activverecord/test/cases/migration/columns_test.rb
