I'm posting a quick hack while I don't find a better solution.

I'm actually using it on my project to avoid breaking textareas and pre tags. Replace ['span', 'a'] with the tags on which you want to prevent indentation.

markup = """
ab
link
link1link2
"""

# Double curly brackets to avoid problems with .format()
stripped_markup = markup.replace('{','{{').replace('}','}}')

stripped_markup = BeautifulSoup(stripped_markup)

unformatted_tag_list = []

for i, tag in enumerate(stripped_markup.find_all(['span', 'a'])):
    unformatted_tag_list.append(str(tag))
    tag.replace_with('{' + 'unformatted_tag_list[{0}]'.format(i) + '}')

pretty_markup = stripped_markup.prettify().format(unformatted_tag_list=unformatted_tag_list)

print pretty_markup
