Making a few assumptions, this does the trick for me:
:g/^{/,/^[^{]/-j
Assumptions:
1) the stray "\" in your results was a mis-type
2) the last line of the file starts with something
other than "{"
3) all the lines with "{...}" are at the beginning-of-line
with no leading space/punctuation
To break that down:
g/ on every line that matches the following pattern
^{ a "{" at the beginning of the line
/ perform the following action
, from the current line through
/^[^{] the next line that doesn't start with a "{"
- adjust the ending line back one
(to exclude the non-"{" line)
j join them together
Hope this helps,
