Error parsing broadcast expressions with getindex

[jondeuce]

Seems to occur for broadcast expressions with more than two arguments within a getindex. Possibly related to #537. MWE:

julia> format_text("a[1 .+ 1]") # okay
"a[1 .+ 1]"

julia> format_text("1 .+ 1 .+ 1") # okay outside of getindex
"1 .+ 1 .+ 1"

julia> format_text("a[1 .+ 1 .+ 1]") # fails
ERROR: Error while PARSING formatted text:

1 a[1 .+ 1.+1]

...

Error occurred on line 1, offset 11 of formatted text.

The error might not be precisely on this line but it should be in the region of the code block. Try commenting the region out and see if that removes the error.

Based on the expression a[1 .+ 1.+1] in the error message, it seems to be deleting space between 1 and .+, leading to the invalid expression 1.+1. In fact, adding parentheses fixes the issue:

julia> format_text("a[1 .+ (1) .+ 1]") # works with extra parenthesis
"a[1 .+ (1).+1]" # note (1).+1 in output, i.e. spaces deleted
